You get Page 1 of 3

Quote:
Two lubricants recommended for the same specification (API SN, for example) do not necessarily provide equal performance and protection, however. Lubricants meeting the specification requirements have only met the minimum performance requirements, leaving room for significant differences in performance. For example, API SN and ILSAC GF-5 require weight lost due to volatility to be no greater than 15 percent. While some oils may barely meet the requirement, AMSOIL Signature Series 5W-30 Synthetic Motor Oil (ASL), for example, demonstrates only 6.9 percent weight loss due to volatility, offering better performance. Those who demand the highest possible performance should dig deeper into each lubricant’s typical technical properties to find the one that offers the best performance.
Reinforcing my view on what tests are ACTUALLY done in the meets/exceeds.
Page 2 and 3 of the "dexos" search become
* VER PÁGINA 25 VER PÁGINA 18
* CHANGE OIL LESS OFTEN.
* Signature Series 100% Synthetic Motor Oil Data Bulletins Pack of 25
And becomes page 2 of 2...???
So where would the casual researcher of Dexos requirements reading their manual be directed ?
